Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648180, here are decompositions:

31 + 8648149 = 8648180
67 + 8648113 = 8648180
97 + 8648083 = 8648180
283 + 8647897 = 8648180
379 + 8647801 = 8648180
397 + 8647783 = 8648180
421 + 8647759 = 8648180
523 + 8647657 = 8648180

Showing the first eight; more decompositions exist.
